WOVEN FYABRIC.

SPECIFICATION forming part of Letters Patent No. 657,940, datedSeptember 18, 1900.

Application filed June 29, 1900- Serial N0. 22,023. (No specimens.)

' T at whom it may concern:

Be it known that 1, ROBERT JOHNSTON, a citizen ofthe United States,residing at the city of Philadelphia, in. the county of Phila- (lelphiaand State of Pennsylvania, have invented certain newand usefulImprovements in Woven Fabrics, of which the following is aspecification.

My invention has relation to a woven fabric, and in such connection itrelates particularly to the structure and-to the arrangement of thewarps and wefts to constitute the fabric of my invention. I

The principal object of my invention is to provide a thick double-facedand homogeneous fabric suitable for portires, couch-covers, and thelike, in which both faces are ornamented or figured by heavywarp-threads, one set of the figuring warp-threads remaining in oneplane to constitute the figure for one face only of the fabric and'theother set remaining in a parallel plane to constitute the figure for theother face of the fabric, and said figuring warp-threads being used inconjunction with weft-threads of alternately heavy and light texture,the heavy or stuffer weft-threads remaining always during the weaving ofthe body of the fabric between the two sets of figuring warp-threads,while the light weft-threads are arrangedin sets of two, one in each setbeing shot above the upper heavy figuring warp-thread, while the otherin each set is shot below the lower heavy Warp-thread, said warp andweft threads be ing combined or united by two light binder warp-threads,which inclose one heavy or stufier weft and one set of two lightweftthreadsin a single set.

My invention, stated in general terms, consists of a woven fabric havingthe structure and with warps and wefts arranged in substantially themanner hereinafter described and claimed.

The nature and scope of my invention will be more fully understood fromthe following description, taken in connection with the accompanyingdrawings, forming part hereof, illustrating in sectional view a fabricembodying the main features of my invention, the section being takenparallel to the warpthreads of the fabric.

Referring to the drawing, a and b are respectively the upper and lowerheavy figuring warp-threads, eachof which, as shown, remains constantlyin one plane to constitute the figure or ornamentation of respectivelythe upper and lower faces of the fabric. Between these two warp-threadsa and b and in the body of the fabric is arranged a series of heavystuft'er weft-threads d. Above the upperwarp a and below the lower warpb are arranged, respectively, the upper and lower light weft-threads eand f, which constitute together a set of light wefts, between which thetwo warps a and b are located. These sets of light wefts are arranged inseries and alternate with the series of heavy stufier-wefts d. A set oflight wefts e f and one stuffer-weft d are tied together in a single setby two light binder-warps g and h, and when so tied the wefts serve tobind the warp-threads a and 1) into a homogeneous structure.

Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

A double-faced, homogeneous woven fabric having both faces figured orornamented by heavy warp-threads, the said fabric consisting of two setsof heavy figuring warpthreads, one set remaining in one plane of thefabric and the other set remaining in the other or parallel plane, aseries of heavy stuffer weft-threads shot between the two sets of heavyWarp-threads, a series of light weftthreads arranged in sets of two andshotinto the fabric in alternate series with the heavy stulfer-wefts,the two weft-threads being arranged respectively above the upperfiguring heavy warp-threads and below the lower figuring heavy warpthreads, and two light binder-warps inclosing one heavy stufferweft andone set of two light weft-threads to bind the warps and wefts into ahomogeneous structure, substantially as and for the purposes described.

In testimony whereof I have'hereunto set my signature in thepresenc'e'of two subscribing' witnesses.

ROBERT JOHNSTON.
